redis_exporter: Export key value/length does not work with Redis cluster.

Describe the problem A node of a Redis cluster can redirect queries to the proper node. A cluster-aware Redis client is expected to connect to the specified node to retry a request. redis_exporter does not support that. Export key value/length does not work with a cluster.

What version of redis_exporter are you running?

1.9.0

Running the exporter ./redis_exporter -redis.addr redis-cluster-endpoint:6379 -check-single-keys channel:updates

yes. The change should be minimal. I will raise a PR and discuss further there.

I will do that. I will share what I am planning to do as soon as it is ready.

Thanks for making me aware of redisc - didn’t know about that.

I’m a little pressed for time right now but I can review and merge a PR for the README if you submit one.
